I'm a manager at a store where we buy and sell used books and media. There's a lot of crazy things that have happened in the year I've worked here, but this is one of the funnier stories. A customer comes in to sell audio books. I placed the ones that had scratched discs in a pile and the ones I bought in another. I called the customer over to let her know her offer was ready. When I explained to her what the piles were, she asked why some of the audiobooks got rejected. As usual, I explained that we can't sell stuff with scratches because there's a chance they don't work and she's welcome to take the rejects back but if she doesn't want them we can donate it away. She accepts the offer, takes the rejected audiobooks, and leaves.

About 30 minutes later she comes back. I don't know what happened in those 30 minutes, but she is really angry. She holds up the audiobooks I passed on and says "just so you know, I originally bought these from here!"

I explain that we try our best to check cds for scratches (even though she doesn't understand that SHE could have been the one to scratch them AFTER buying them from us) but stuff does slip through the cracks and sometimes we sell stuff that shouldn't have been priced and put on the floor (which is why we allow refunds). She gets even angrier and starts accusing me personally for the reason why her audiobooks are scratched because I "wasn't doing my job right" before she came in and bought them months ago (which obviously makes no sense). I wasn't even sure what she intended to get out of this conversation, besides telling me I don't know what I'm doing.....she didn't want a refund, she had already cashed out her voucher, and she had already bought more stuff.

I eventually get fed up and looked at her rejected audiobooks and noticed that she had bought them from ANOTHER USED BOOKSTORE. When I pointed out the sticker and said "these actually came from _____, they weren't even ours," she was speechless, embarrassed and stormed out.

This happened maybe 7 years ago but I still remember it like it because of the whole situation, because it happened over the course of two days. I work in a well known discount supermarket and on both days I was on the till. A customer comes in with a toaster. I'll be Me, customer will be C.

C: I want to return this toaster.

Me: OK, is there anything wrong with it?

C: It's burning the bread at every setting. Doesn't matter what setting I put it at, it burns the bread.

Me: OK, I'll need to get my manager to authorise the refund for me.

We need a manager to authorise any refunds over a certain amount. It was the store manager at the time and instead of authorising the refund as I thought they would, explained to the customer that he's going to test it. Bit strange I thought but I was new to the store at the time so didn't think much of it. So the manager grabs some bread off the shelf and goes in the back with the toaster. Maybe 5 minutes later, manager comes back with a piece of bread. And says to the customer that he just tested the toaster at the lowest setting and that was the piece of bread he tried to see if it was burning the toast. The customer wasn't having any of it and stuck by what they had said that the toast was burning the bread. This happened maybe two or three more times: Manager would put bread in toaster at a different setting, come out with bread unburnt, customer sticking to their guns. It got to the stage that the customer went through the back with the manager to see what they were doing. In the end the customer didn't get the refund and had to leave with the toaster.

Two days pass, I'm on the till again and guess who's back, this time with their wife. Who also had the believe that the toaster was faulty. The store manager who dealt with the customer was also in so I got them to deal with the customer again. This next part might seem made up, but I promise you it happened. The wife was armed with a piece of bread she had done in the toaster (which wasn't burnt in anyway, it was more white than anything) and she was asking people who were in my queue at the time if they would eat the toast. Everyone she asked said yes and she wasn't happy about it. So the store manager, a deputy manager, the customer and his wife all went into the back to essentially watch a toaster do what it does, which is toast bread. By this time I'm trying my best to hold back a fit of giggles as I couldn't believe that was actually happening. In the end they had to take the toaster back and not get a refund as there was clearly nothing wrong with it. I don't know if they had both gotten one and were trying to return one by saying it was faulty. Or if they thought it was faulty because they weren't putting it at the correct setting for how they like their toast. I don't know and guess I'll never know.

Tl;dr - A customer tried to bring back a toaster claiming it was faulty, when it wasn't so store manager doesn't give them their money back. Comes back in a few days later with his wife to repeat the whole situation and still doesn't get their money back.
